Thirteen substantial tales, 1953-85, from short to novella length, showing Norton's complete range from sword and sorcery to science fiction. Most of the tales here, per Norton's usual style, feature strong, positive female leads. Exiled noblewoman Hertha seeks sorcerous help to avenge herself--rather predictably--on the man who raped her; a sequel involves Hertha's changeling daughter. A rousing long yarn follows the blind weaver-witch Dairine's adventures among carnivorous, spider-like alien weavers of rare skill. The lonely, confused, magical girl Tursla seeks her destiny in clues from her past, her ancestry, and her dreams. A witch rescues her imperiled lover in the magically dangerous country of the Old Ones. Also in a fantasy vein: a Witch World Sulcar woman and Falconer man who must cooperate to survive; an ensorcelled hero of Ithkar; sorcery and cats; and Baltic witchcraft. On the fantasy/sf border is the title piece: rebellious psi-powered "esper" and escaped slave Craike fall through an interdimensional doorway as pursuers close in. Orthodox sf: crossbred hive-human Tamisan's power is to project her dreams to include others; talented Steena bests an invisible monster aboard a mysteriously abandoned spaceship; and a male-lead Martian adventure. Norton has only one gear--Forward: slow--and she's often overbearingly YA-ish; but the short/medium-length format shows off her real yet limited talents to best advantage.
